Final Invert Tank Conclusions
By: Aaron and Claire
Intro: Background info
● Hands on display that grabbed people's attention to learn
● Test the relationships and territories of 3 different species of shrimp
● See if a symbiotic relationship could be made between snapping shrimp and gobies
● Create a diverse ecosystem with many different relationships and territories
Info on organisms ● Sexy shrimp and their
relationships with anemones and corals in the tank (Seona Choi)
● Snapping Shrimp and goby symbiotic relationship and territory (http://www.practicalfishkeeping.co.uk/content.php?sid=5250)
● Peppermint shrimp and their relationship with other species of shrimp
Research Questions 1. Can multiple types of shrimp live together, will they fight, or will they become territorial?
2. Pistol shrimp and gobies have mutualistic relationships, will the other species of shrimp attack
these gobies? Will the shrimp take the gobies? What will the gobies do?
3. Will we need to add more hiding places for the shrimp?
4. If the shrimp become aggressive, how can we prevent it and how can we find a solution that will
help them to coexist?
5. how is a mutualistic relationship between two organisms of different species, in this case shrimp
and goby, “working together” to benefit from the relationship (McGinley, 2014)?
Hypothesis
1. The behavior of shrimp in symbiosis and the behavior of shrimp that are solitary
will be observed in this experiment. Shrimp with symbioses will behave differently
than the shrimp that are solitary.
2. The symbiotic relationships created by our selection of animals will be mutualistic
and beneficial to both parties involved in each relationship. For example, the goby
uses the pistol shrimp burrow for protection from predators, the goby acts as
"eyes" for the pistol shrimp (Smith, 2014).
Materials and Experiments Materials: acclimation tank, sump, protein skimmers, sock filters, live rock, live sand, sponges, activated carbon, heater, lifeguard, etc. mysis shrimp, seaweed, and tongs Experiments: PH kits, alkalinity kits, hydrometer, and refractometer. These will be used to make sure the tank is always a safe environment for our ecosystem, in order for our experiment to thrive.
Data collection Shrimp and organism behavior will be observed and
recorded on a data sheet, this will have a diagram of the
tank on the back in order to draw the location of
organisms: Do they hide, and if so, where? Do they swim?
Do they pair up? Do they stay solitary? Do they form their
mutual relationships? Do they stay in similar areas? Do
they fight over food? How do they behave during the night
vs. day? How do they react to different lighting? What are
their eating habits going to be? Daily draw diagrams of the
tank to measure migration, hiding places, etc.
Results: review questions 1. Can multiple types of shrimp live together, will they fight, or will they become territorial?
2. Pistol shrimp and gobies have mutualistic relationships, will the other species of shrimp attack
these gobies? Will the shrimp take the gobies? What will the gobies do?
3. Will we need to add more hiding places for the shrimp?
4. If the shrimp become aggressive, how can we prevent it and how can we find a solution that will
help them to coexist?
5. How is a mutualistic relationship between two organisms of different species, in this case
shrimp and goby, “working together” to benefit from the relationship (McGinley, 2014)?
amount of a certain species in that territory 63 days total = percent of time spent in that territory
63 days total of recorded observation before, during, and after schooltank lights were mostly on when observations were taken
How we collected our data
**pass around an example of a filled out data sheet
example:
Hiding under rocks
show video of snapping going under the rock
On Corals
show video of sexy on corals
In caves/burrows
show video of snapper coming out of the cave
Below and sifting sand
show video of the conch feeding
With other organisms
point out where the sexies were drawn on the observation sheet all on same corals
discuss the symbiotic relationships between different organisms
Feeding
point out which animals have to be fed vs. eating within the tank
conclusion: reflection on hypothesis
1. The behavior of shrimp in symbiosis and the behavior of shrimp that are solitary
will be observed in this experiment. Shrimp with symbioses will behave differently
than the shrimp that are solitary.
2. The symbiotic relationships created by our selection of animals will be mutualistic
and beneficial to both parties involved in each relationship. For example, the goby
uses the pistol shrimp burrow for protection from predators, the goby acts as
"eyes" for the pistol shrimp (Smith, 2014).
if we were to keep going...
challenges ● our project isn’t very specific so it was hard to
come up with a plan to collect data and actually make an experiment
● we couldn’t find one snapping shrimp for a while● we couldn't find the first goby for a while/we
didn’t have one● the snapping shrimp would mostly be hidden● the salinity dropped low for about a week
